The above is the equivalent of activating the address bar and hitting Return in each tab. If you open up a new window, open sites in two new tabs, scroll to the bottom of every page and then run the script you should see the loading bar in the active tab and then when you switch to the other tabs they should be back at the top of their page again (tested in Ventura/Safari 16.1).
If you're seeing something else -- what? If you're seeing that but expecting something else -- what?
